Our Virtual Color Roundtable

The number of things you can do with color in today’s world is growing daily. It’s not just about creating a look anymore, it’s using color to tell or enhance a story. And because filmmakers recognize this power, they are getting colorists involved in the process earlier than ever before. And while the industry is excited about HDR and all it offers, this process also creates its own set of challenges and costs.

To find out what those in the trenches are thinking, we reached out to makers of color gear as well as hands-on colorists with the same questions, all in an effort to figure out today’s trends and challenges.

Company 3 Senior Colorist Stephen NakamuraCompany 3 is a global group of creative studios specializing in color and post services for features, TV and commercials.

How has the finishing of color evolved most recently?
By far, the most significant change in the work that I do is the requirement to master for all the different exhibition mediums. There’s traditional theatrical projection at 14 footlamberts (fL) and HDR theatrical projection at 30fL. There’s IMAX. For home video, there’s UHD and different flavors of HDR. Our task with all of these is to master the movie so it feels and looks the way it’s supposed to feel and look on all the different formats.

There’s no one-size-fits-all approach. The colorist’s job is to work with the filmmakers and make those interpretations. At Company 3 we’re always creating custom LUTs. There are other techniques that help us get where we need to be to get the most out of all these different display types, but there’s no substitute for taking the time and interpreting every shot for the specific display format.

How has laser projection and HDR impacted the work? And do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
Not too long ago, a cinematographer could expose an image specifically for one display format — a film print projected at 14fL. They knew exactly where they could place their highlights and shadows to get a precise look onscreen. Today, they’re thinking in terms of the HDR version, where if they don’t preserve detail in the blacks and whites it can really hurt the quality of the image in some of the newer display methods.

I work frequently with Dariuisz Wolski (Sicario: Day of the Soldado, All the Money in the World). We’ve spoken about this a lot, and he’s said that when he started shooting features, he often liked to expose things right at the edge of underexposure because he knew exactly what the resulting print would be like. But now, he has to preserve the detail and fine-tune it with me in post because it has to work in so many different display formats.

There are also questions about how the filmmakers want to use the different ways of seeing the images. Sometimes they really like the qualities of the traditional theatrical standard and really don’t want HDR to look very different and to make the most of the dynamic range. If we have more dynamic range, more light, to work with, it means that in essence we have a larger “canvas” to work on. But you need to take the time to individually treat every shot if you want to get the most out of that “canvas.”

Where do you see the industry moving in the near future?
The biggest change I expect to see is the development of even brighter, higher-contrast exhibition mediums. At NAB, Sony unveiled this wall of LED panels that are stitched together without seams and can display up to 1000 nits. It can be the size of a screen in a movie theater. If that took off, it could be a game changer. If theatrical exhibition gets better with brighter, higher-contrast screens, I think the public will enjoy it, provided that the images are mastered appropriately.

Sicario: Day of the Soldado

What is the biggest challenge you see for the color grading process now and beyond?
As there are more formats, there will be more versions of the master. From P3 to Rec.709 to HDR video in PQ — they all translate color information differently. It’s not just the brightness and contrast but the individual colors. If there’s a specific color blue the filmmakers want for Superman’s suit, or red for Spiderman, or whatever it is, there are multiple layers of challenges involved in maintaining those across different displays. Those are things you have to take a lot of care with when you get to the finishing stage.

What’s the best piece of work you’ve seen that you didn’t work on?
I know it was 12 years ago now, but I’d still say 300, which was colored by Company 3 CEO Stefan Sonnenfeld. I think that was enormously significant. Everyone who has seen that movie is aware of the graphic-novel-looking imagery that Stefan achieved in color correction working with Zack Snyder and Larry Fong.

We could do a lot in a telecine bay for television, but a lot of people still thought of digital color correction for feature films as an extension of the timing process from the photochemical world. But the look in 300 would be impossible to achieve photo-chemically, and I think that opened a lot of people’s minds about the power of digital color correction.

How has the finishing of color evolved most recently?
Traditionally, there has been such a huge difference between the color finishing process for television production verses for cinematic release. It used to be that a target format was just one thing, and finishing for TV was completely different than finishing for the cinema.

Colorists working on theatrical films will spend most of their efforts on grading for projection, and only after there is a detailed trim pass to make a significantly different version for the small screen. Television colorists, who are usually under much tighter schedules, will often only be concerned with making Rec.709 look good on a standard broadcast monitor. Unless there is a great deal of care to preserve the color and dynamic range of the digital negative throughout the process, the Rec.709 grade will not be suitable for translation to other expanded formats like HDR.

Now, there is an ever-growing number of distribution formats with different color and brightness requirements. And with the expectation of delivering to all of these on ever-tighter production budgets, it has become important to use color management techniques so that the work is not duplicated. If done properly, this allows for one grade to service all of these requirements with the least amount of trimming needed.

How has laser projection and HDR impacted the work?
HDR display technology, in my opinion, has changed everything. The biggest impact on color finishing is the need for monitoring in both HDR and SDR in different color spaces. Also, there is a much larger set of complex delivery requirements, along with the need for greater technical expertise and capabilities. Much of this complexity can be reduced by having the tools that make the various HDR image transforms and complex delivery formats as automatic as possible.

Color management is more important than ever. Efficient and consistent workflows are needed for dealing with multiple sources with unique color sciences, integrating visual effects and color grading while preserving the latitude and wide color gamut of the image.

The color toolset should support remapping to multiple deliverables in a variety of color spaces and luminance levels, and include support for dynamic HDR metadata systems like Dolby and HDR10+. As HDR color finishing has evolved, so has the way it is delivered to studios. Most commonly it is delivered in an HDR IMF package. It is common that Rec.2020 HDR deliverables be color constrained to the P3 color volume and also that Light Level histograms and HDR QC reports be delivered.

Do you feel DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
Not as much as you would think. Two things are working against this. First, film and high-end digital cameras themselves have for some time been capturing latitude suitable for HDR production. Proper camera exposure is all that is needed to ensure that an image with a wide enough dynamic range is recorded. So from a capture standpoint, nothing needs to change.

The other is cost. There are currently only a small number of suitable HDR broadcast monitors, and most of these are extremely expensive and not designed well for the set. I’m sure HDR monitoring is being used on-set, but not as much as expected for productions destined for HDR release.

Also, it is difficult to truly judge HDR displays in a bright environment, and cinematographers may feel that monitoring in HDR is not needed full time. Traditionally with film production, cinematographers became accustomed to not being able to monitor accurately on-set, and they rely on their experience and other means of judging light and exposure. I think the main concern for cinematographers is the effect of lighting choices and apparent resolution, saturation and contrast when viewed in HDR.

Highlights in the background can potentially become distracting when displayed at 1000 nits verses being clamped at 100. Framing and lighting choices are informed by proper HDR monitoring. I believe we will see more HDR monitoring on-set as more suitable displays become available.

Where do you see the industry moving in the near future?
Clearly HDR display technology is still evolving, and we will see major advances in HDR emissive displays for the cinema in the very near future. This will bring new challenges and require updated infrastructure for post as well as the cinema. It’s also likely that color finishing for the cinema will become more and more similar to the production of HDR for the home, with only relatively small differences in overall luminance and the ambient light of the environment.

Looking forward, standard dynamic range will eventually go away in the same way that standard definition video did. As we standardize on consumer HDR displays, and high-performance panels become cheaper to make, we may not need the complexity of HDR dynamic remapping systems. I expect that headset displays will continue to evolve and will become more important as time goes on.

What is the biggest challenge you see for the color grading process now and beyond?
We are experiencing a period of change that can be compared to the scope of change from SD to HD production, except it is happening much faster. Even if HDR in the home is slow to catch on, it is happening. And nobody wants their production to be dated as SDR-only. Eventually, it will be impossible to buy a TV that is not HDR-capable.

Aside from the changes in infrastructure, colorists used to working in SDR have some new skills to learn. I think it is a mistake to do separate grading versions for every major delivery format. Even though we have standards for HDR formats, they will continue to evolve, so post production must evolve too. The biggest challenge is meeting all of these different delivery requirements on budgets that are not growing as fast as the formats.

How has the finishing of color evolved most recently?
It’s interesting that you use the term “finishing of color.” In my clients’ world, finishing and color now go hand in hand. My commercial clients expect not only a great grade but seamless VFX work in finalizing their spots. Both of these are now often taking place with the same artist. Work has been pushed from just straight finishing with greenscreen, product replacement and the like to doing a grade up to par with some of the higher-end coloring studios. Price is pushing vastly separate disciplines into one final push.

Clients now expect to have a rough look ready not only of the final VFX, but also of the color pass before they attend the session. I usually only do minor VFX tweaks when clients arrive. Sending QuickTimes back and forth between studio and client usually gets us to a place where our client, and their client, are satisfied with at least the direction if not the final composites.

Color, as a completely subjective experience, is best enjoyed with the colorist in the room. We do grade some jobs remotely, but my experience has clearly been that from both time and creativity standpoints, it’s best to be in the grading suite. Unfortunately, recently due to time constraints and budget issues, even higher-end projects are being evaluated on a computer/phone/tablet back at the office. This leads to more iterations and less “the whole is greater than the sum of the parts” mentality. Client interaction, especially at the grading level, is best enjoyed in the same room as the colorist. Often the final product is markedly better than what either could envision separately.

Where do you see the industry moving in the near future?
I see the industry continuing to coalesce around multi-divisional companies that are best suited to fulfill many clients’ needs at once. Most projects that come to us have diverse needs that center around one creative idea. We’re all just storytellers. We do our best to tell the client’s story with the best talent we offer, in a reasonable timeframe and at a reasonable cost.

The future will continue to evolve, putting more pressure on the editorial staff to deliver near perfect rough cuts that could become finals in the not-too-distant future.

The tools continue to level the playing field. More generalists will be trained in disciplines including video editing, audio mixing, graphic design, compositing and color grading. This is not to say that the future of singularly focused creatives is over. It’s just that those focused creatives are assuming more and more responsibilities. This is a continuation of the consolidation of roles that has been going on for several years now.

What is the biggest challenge you see for the color grading process now and beyond?
The biggest challenge going forward is both technical and budgetary. Many new formats have emerged, including the new ProRes RAW. New working color spaces have also emerged. Many of us work without on-staff color scientists and must find our way through the morass of HDR, ACES, Scene Linear and Rec.709. Working with materials that round trip in-house is vastly easier than dealing with multiple shops all with their own way of working. As we collaborate with outside shops, it behooves us to stay at the forefront of technology.

But truth be told, perhaps the biggest challenge is keeping the creative flow and putting the client’s needs first. Making sure the technical challenges don’t get in the way. Clients need to see a seamless view without technical hurdles.

What’s the best piece of work you’ve seen that you didn’t work on?
I am constantly amazed at the quality of work coming out of Netflix. Some of the series are impeccably graded. Early episodes of Bloodline, which was shot with the Sony F65, come to mind. The visuals were completely absorbing, both daytime and nighttime scenes.

How has the finishing of color evolved most recently?
While it used to be a specialized suite in a post facility, color finishing has evolved tremendously over the last 10 years with low-cost access to powerful systems like Resolve for use on-set in commercial finishing to final DI color grading. These systems have evolved from being more than just color. Now they are editorial, sound mixing and complete finishing platforms.

How has laser projection and HDR impacted the work?
Offering brighter images in the theatre and the home with laser projection, OLED walls and HDR displays will certainly change the viewers’ experience, and it has helped create more work in post, offering up another pass for grading.

However, brighter images also show off image artifacts and can bring attention to highlights that may already be clipping. Shadow detail that was graded in SDR may now look milky in HDR. These new display mediums require that you spend more time optimizing the color correction for both display types. There is no magic one grade fits all.

Do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
I think cinematographers are still figuring this out. Much like color correction between SDR and HDR, lighting for the two is different. A window that was purposely blown out in SDR, to hide a lighting rig outside, may show up in HDR, exposing the rig itself. Color correction might be able to correct for this, but unless a cinematographer can monitor in HDR on-set, these issues will come up in post. To do it right, lighting optimization between the two spaces is required, plus SDR and HDR monitoring on-set and near-set and in editorial.

Where do you see the industry moving in the near future?
It’s all about content. With the traditional studio infrastructure and broadcast television market changing to Internet Service Providers (ISPs), the demand for content, both original and HDR remastered libraries, is helping prop up post production and is driving storage- and cloud-based services.

Codex’s ColorSynth and Media Vault

In the long term, if the competition in this space continues and the demand for new content keeps expanding, traditional post facilities will become “secure data centers” and managed service providers. With cloud-based services, the talent no longer needs to be in the facility with the client. Shared projects with realtime interactivity from desktop and mobile devices will allow more collaboration among global-based productions.

What is the biggest challenge you see for the color grading process now and beyond?
Project management — sharing color set-ups among different workstations. Monitoring of the color with proper calibrated displays in both SDR and HDR and in support of multiple deliverables is always a challenge. New display technologies, like laser projection and new Samsung and Sony videowalls, may not be cost effective for the creative community to access for final grading. Only certain facilities may wind up specializing in this type of grading experience, limiting global access for directors and cinematographers to fully visualize how their product will look like on these new display mediums. It’s a cost that may not get the needed ROI, so in the near future many facilities may not be able to support the full demand of deliverables properly.

Blackmagic Director of Sales/Operations Bob CanigliaBlackmagic creates DaVinci Resolve, a solution that combines professional offline and online editing, color correction, audio post production and visual effects in one software tool.

How has the finishing of color evolved most recently?
The ability to work in 8K, and whatever flavor of HDR you see, is happening. But if you are talking evolution, it is about the ability to collaborate with everyone in the post house, and the ability to do high-quality color correction anywhere. Editors, colorists, sound engineers and VFX artists should not be kept apart or kept from being able to collaborate on the same project at the same time.

New collaborative workflows will speed up post production because you will no longer need to import, export or translate projects between different software applications.

How has laser projection and HDR impacted the work?
The most obvious impact has been on the need for colorists to be using software that can finish a project in whatever HDR format the client asks for. That is the same with laser projection. If you do not use software that is constantly updating to whatever new format is introduced, being able to bid on HDR projects will be hard.

HDR is all about more immersive colors. Any colorist should be ecstatic to be able to work with images that are brighter, sharper and with more data. This should allow them to be even more creative with telling a story with color.

Do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
As for cinematographers, HDR gives viewers a whole new level of image details. But that hyper reality could draw the viewer from the wanted target in a shot. The beautiful details shining back on a coffee pot in a tracking shot may not be worth worrying about in SDR, but in HDR every shot will create more work for the colorist to make sure the viewer doesn’t get distracted by the little things. For DPs, it means they are going to have to be much more aware of lighting, framing and planning the impact of every possible item and shadow in an image.

Where do you see the industry moving in the near future?
Peace in our time amongst all of the different post silos, because those silos will finally be open. And there will be collaboration between all parts of the post workflow. Everyone — audio, VFX, editing and color correction — can work together on the same project seamlessly.

For example, in our Resolve tool, post pros can move between them all. This is what we see happening with colorists and post houses right now, as each member of the post team can be much more creatively flexible because anyone can explore new toolsets. And with new collaboration tools, multiple assistants, editors, colorists, sound designers and VFX artists can all work on the same project at the same time.

Resolve 15

For a long-term view, you will always have true artists in each of the post areas. People who have mastered the craft and can separate themselves as being color correction artists. What is really going to change is that everyone up and down the post workflow at larger post houses will be able to be much more creative and efficient, while small boutique shops and freelancers can offer their clients a full set of post production services.

What is the biggest challenge you see for the color grading process now and beyond?
Speed and flexibility. Because with everyone now collaborating and the colorist being part of every part of the post process, you will be asked to do things immediately… and in any format. So if you are not able to work in real time or with whatever footage format thrown at you, they will find someone who can.

This also comes with the challenge of changing the old notion that the colorist is one of the last people to touch a project. You will be asked to jump in early and often. Because every client would love to show early edits that are graded to get approvals faster.

FilmLight CEO Wolfgang LemppFilmLight designs, creates and manufactures color grading systems, image processing applications and workflow tools for the film and television industry

How has the finishing of color evolved recently?
When we started FilmLight 18 years ago, color management was comparatively simple: Video looked like video, and digital film was meant to look like film. And that was also the starting point for the DCI — the digital cinema standard tried to make digital projection look exactly like conventional cinema. This understanding lasted for a good 10 years, and even ACES today is very much built around film as the primary reference. But now we have an explosion of new technologies, new display devices and new delivery formats.

There are new options in resolution, brightness, dynamic range, color gamut, frame rate and viewing environments. The idea of a single deliverable has gone: There are just too many ways of getting the content to the viewer. That is certainly affecting the finishing process — the content has to look good everywhere. But there is another trend visible, too, which here in the UK you can see best on TV. The color and finishing tools are getting more powerful and the process is getting more productive. More programs than ever before are getting a professional color treatment before they go out, and they look all the better for it.

Either way, there is more work for the colorist and finishing house, which is of course something we welcome.

How has laser projection and HDR impacted the work?
Laser projection and HDR for cinema and TV are examples of what I described above. We have the color science and the tools to move comfortably between these different technologies and environments, in that the color looks “right,” but that is not the whole story.

The director and DP will choose to use a format that will best suit their story, and will shoot for their target environment. In SDR, you might have a bright window in an interior scene, for example, which will shape the frame but not get in the way of the story. But in HDR, that same window will be too bright, obliterate the interior scene and distract from the story. So you would perhaps frame it differently, or light up the interior to restore some balance. In other words, you have to make a choice.

HDR shouldn’t be an afterthought, it shouldn’t be a decision made after the shoot is finished. The DP wants to keep us on the edge of our seats — but you can’t be on the edge in HDR and SDR at the same time. There is a lot that can be done in post, but we are still a long way from recreating the multispectral, three-dimensional real world from the output of a camera.

HDR, of course, looks fantastic, but the industry is still learning how to shoot for best effect, as well as how to serve all the distribution formats. It might well become the primary mastering format soon, but SDR will never go away.

Where do you see the industry moving in the future?
For me, it is clear that as we have pushed resolution, frame rate, brightness and color gamut, it has affected the way we tell stories. Less is left to the imagination. Traditional “film style” gave a certain pace to the story, because there was the expectation that the audience was having to interpret, to think through to fill in the black screen in between.

Now technology has made things more explicit and more immersive. We now see true HDR cinema technology emerging with a brightness of 600 nits and more. Technology will continue to surge forward, because that is how manufacturers sell more televisions or projectors — or even phones. And until there is a realistic simulation of a full virtual reality environment, I don’t see that process coming to a halt. We have to be able to master for all these new technologies, but still ensure compatibility with existing standards.

What is the biggest challenge for color grading now and in the future?
Color grading technology is very much unfinished business. There is so much that can be done to make it more productive, to make the content look better and to keep us entertained.

Blackboard

As much as we might welcome all the extra work for our customers, generating an endless stream of versions for each program is not what color grading should be about. So it will be interesting to see how this problem will be solved. Because one way or another, it will have to be. But while this is a big challenge, it hopefully isn’t what we put all our effort into over the coming years.

BlackboardThe real challenge is to understand what makes us appreciate certain images over others. How composition and texture, how context, noise and temporal dynamics — not just color itself — affect our perception.

It is interesting that film as a capture medium is gaining popularity again, especially large-format capture. It is also interesting that the “film look” is still precious when it comes to color grading. It puts all the new technology into perspective. Filmmaking is storytelling. Not just a window to the world outside, replaced by a bigger and clearer window with new technology, but a window to a different world. And the colorist can shape that world to a degree that is limited only by her imagination.

Olympusat Entertainment Senior DI Colorist Jim WicksA colorist since 2007, Jim has been a senior DI colorist at Olympusat Entertainment since 2011. He has color restored hundreds of classic films and is very active in the color community.

How has the finishing of color evolved most recently?
The phrase I’m keying in on in your question is “most recently.” I believe the role of a colorist has been changing exponentially for the last several years, maybe longer. I would say that we are becoming, if we haven’t already, more like finishing artists. Color is now just one part of what we do. Because technologies are changing more rapidly than at any time I’ve witnessed, we now have a lot to understand and comprehend in addition to just color. There is ACES, HDR, changing color spaces, integrating VFX workflows into our timelines, laser projection and so on. The list isn’t endless, and it’s growing.

How has laser projection and HDR impacted the work?
For the time being, they do not impact my work. I am currently required to deliver in Rec.709. However, within that confine I am grading a wider range of media than ever before, such as 2K and 4K uncompressed DPX; Phantom Digital Video Files; Red Helium 8K in the IPP2 workspace; and much more. Laser projection and HDR is something that I continue to study by attending symposiums, or wherever I can find that information. I believe laser projection and HDR are important to know now. When the opportunity to work with laser projection and HDR is available to me, I plan to be ready.

Do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
Of course! At the very heart of every production, the cinematographer is the creator and author of the image. It is her creative vision. The colorist is the protector of that image. The cinematographer entrusts us with her vision. In this respect, the colorist needs to be in sync with the cinematographer as never before. As cinematographers move because of technology, so we move. It’s all about the deliverable and how it will be displayed. I see no benefit for the colorist and the cinematographer to not be on the same page because of changing technology.

Where do you see the industry moving in the near future and the long-range future?
In the near future: HDR, laser projection, 4K and larger and larger formats.

In the long-range future: I believe we only need to look to the past to see the changes that are inevitably ahead of us.

Technological changes forced film labs, telecine and color timers to change and evolve. In the nearly two decades since O Brother Where Art Thou? we no longer color grade movies the way we did back when the Coen classic was released in 2000. I believe it is inevitable: Change begets change. Nothing stays the same.

In keeping with the types of changes that came before, it is only a matter of time before today’s colorist is forced to change and evolve just as those before us were forced to do so. In this respect I believe AI technology is a game-changer. After all, we are moving towards driverless cars. So, if AI advances the way we have been told, will we need a human colorist in the future?

What is the biggest challenge you see for the color grading process now and beyond?
Not to sound like a “get off my lawn rant,” but education is the biggest challenge, and it’s a two-fold problem. Firstly, at many fine film schools in the US color grading is not taught as a degree-granting course, or at all.

Secondly, the glut of for-profit websites that teach color grading courses have no standardized curriculum, which wouldn’t be a problem, but at present there is no way to measure how much anyone actually knows. I have personally encountered individuals who claim to be colorists and yet do not know how to color grade. As a manager I have interviewed them — their resumes look strong, but their skills are not there. They can’t do the work.

What’s the best piece of work you’ve seen that you didn’t work on?
Just about anything shot by Roger Deakins. I am a huge fan of his work. Mitch Paulson and his team at Efilm did great work on protecting Roger’s vision for Blade Runner 2049.

Colorist David RiveroThis Madrid-born colorist is now based in China. He color grades and supervises the finishing of feature films and commercials, normally all versions, and often the trailers associated with them.

How has the finishing of color evolved most recently?
The line between strictly color grading and finishing is getting blurrier by the year. Although it is true there is still a clearer separation in the commercial world, on the film side the colorist has become the “de facto” finishing or supervising finishing artist. I think it is another sign of the bigger role the color grading is starting to play in post.

In the last two to three years I’ve noticed that fewer clients are looking at it as an afterthought, or as simply “color matching.” I’ve seen how the very same people went from a six- to seven-day DI schedule five years ago to a 20-day schedule now. The idea that spending a relatively small amount of extra time and budget on the final step can get you a far superior result is finally sinking in.

The tools and technology are finally moving into a “modern age” of grading:
– HDR is a game changer on the image-side of things, providing a noticeable difference for the audience and a different approach on our side on how to deal with all that information.

– The eventual acceptance by all color systems of what was traditionally compositing or VFX tools is also a turning point, although controversial. There are many that think that colorists should focus on grading. However, I think that rather than colorists becoming compositors, it is the color grading concept and mission that is (still) evolving.

How has laser projection and HDR impacted the work? And do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
Well, on my side of the world (China), the laser and HDR technologies are just starting to get to the public. Cinematographers are not really changing how they work yet, as it is a very small fraction of the whole exhibition system.

As for post, it requires a more careful way of handling the image, as it needs higher quality plates, compositions, CG, VFX, a more careful grade, and you can’t get away with as many tricks as you did when it was just SDR. The bright side is the marvelous images, and how different they can be from each other. I believe HDR is totally compatible with every style you could do in SDR, while opening the doors to new ones. There are also different approaches on shooting and lighting for cinematographers and CG artists.

Goldbuster

The biggest challenge it has created has been on the exhibition side in China. Although Dolby cinemas (Vision+Atmos) are controlled and require a specific pass and DCP, there are other laser projection theaters that show the same DCP being delivered to common (xenon lamp) theaters. This creates a frustrating environment. For example, during the 3D grading, you not only need to consider the very dark theaters with 3FL-3.5FL, but also the new laser rooms that are racking up their lamps to show off why they charge higher ticket prices with to 7FL-8FL.

Where do you see the industry moving in the near future and the long-range future?
I hope to see the HDR technologies settling and becoming the new standard within the next five to six years, and using this as the reference master from which all other deliveries are created. I also expect all these relative new practices and workflows (involving ACES, EXRs with the VFX/CG passes, non-LUT deliveries) to become more standardized and controlled.

In the long term, I could imagine two main changes happening, closely related to each other:
– The concept of grading and colorist, especially in films or long formats, evolving in importance and relationship within the production. I believe the separation or independence between photography and grading will get wider (and necessary) as tools evolve and the process is more standardized. We might get into something akin to how sound editors and sound mixers relate and work together on the sound.

– The addition of (serious) compositing in essentially all the main color systems is the first step towards the possibilities of future grading. A feature like the recent FaceRefinement in Resolve is one of the things I dreamed about five or six years ago.

What is the biggest challenge you see for the color grading process now and beyond?
Nowadays one of the biggest challenges is possibly the multi-mastering environment, with several versions on different color spaces, displays and aspect ratios. It is becoming easier, but it is still more painful than it should be.

Shrinking margins is something that also hurts the whole industry. We all work thanks to the benefits, but cutting on budgets and expecting the same results is not something that is going to happen.

What’s the best piece of work you’ve seen that you didn’t work on?The Revanant, Mad Max, Fury and 300.

How has the finishing of color evolved most recently?
It is always evolving, and the tools are becoming ever more powerful, and camera formats are becoming larger with more range and information in them. Probably the most significant evolution I see is a greater understanding of color science and color space workflows.

How has laser projection and HDR impacted the work? And do you feel that DPs are working differently now that laser projection and the home HDR experiences are becoming more relevant?
These elements impact how footage is viewed and dealt with in post. As far as I can see, it isn’t affecting how things are shot.

Where do you see the industry moving in the near future? What about in the long-range future?
I see formats becoming larger, viewing spaces and color gamuts becoming wider, and more streaming- and laptop-based technologies and workflows.

What is the biggest challenge you see for the color grading process now and beyond?
The constant challenge is integrating the space you traditionally color grade in to how things are viewed outside of this space.

How has the finishing of color evolved most recently?
SDR grading in Rec.709 and 2.4 Gamma is still here, still looks great, and will be prominent for a long time. However, I think we’re becoming more aware of how exciting grading in HDR is, and how many creative doors it opens. I’ve noticed a feeling of disappointment when switching from an HDR to an SDR version of a project, and wondered for a second if I’m accidentally viewing the ungraded raw footage, or if my final SDR grade is actually as flat as it appears to my eyes. There is a dramatic difference between the two formats.

HDR is incredible because you can make the highlights blisteringly hot, saturate a color to nuclear levels or keep things mundane and save those heavier-handed tools in your pocket for choice moments in the edit where you might want some extra visceral impact.

In one sense, cinematographers don’t need to do anything differently. Colorists are able to create high-quality SDR and HDR interpretations of the exact same source footage, so long as it was captured in a high-bit-depth raw format and exposed well. We’re even seeing modern HDR reimaginings of classic films. Movies as varied in subject matter as Saving Private Ryan and the original Blade Runner are coming back to life because the latitude of classic film stocks allows it. However, HDR has the power to greatly exaggerate details that may have otherwise been subtle or invisible in SDR formats, so some extra care should be taken in projects destined for HDR.

Extra contrast and shadow detail mean that noise is far more apparent in HDR projects, so ISO and exposure should be adjusted on-set accordingly. Also, the increased highlight range has some interesting consequences in HDR. For example, large blown-out highlights, such as overexposed skies, can look particularly bad. HDR can also retain more detail and color in the upper ranges in a way that may not be desirable. An unremarkable, desaturated background in SDR can become a bright, busy and colorful background in HDR. It might prove distracting to the point that the DP may want to increase his or her key lighting on the foreground subjects to refocus our attention on them.

Where do you see the industry moving in the near future? What about the long-range future?
I foresee more widespread adoption of HDR — in a way that I don’t with 3D and VR — because there’s no headset device required to feel and enjoy it. Having some HDR nature footage running on a loop is a great way to sell a TV in Best Buy. Where the benefits of another recent innovation, 4K, are really only detectable on larger screens and begin to deteriorate with the slightest bit of compression in the image pipeline, HDR’s magic is apparent from the first glance.

I think we’ll first start to see HDR and SDR orders on everything, then a gradual phasing out of the SDR deliverables as the technology becomes more ubiquitous, just like we saw with the standard definition transition to HD.

For the long-range, I wouldn’t be surprised to see a phasing out of projectors as LED walls become more common for theater exhibitions due to their deeper black levels. This would effectively blur the line between technologies available for theater and home for good.

What is the biggest challenge you see for the color grading process now and beyond?
The lack of a clear standard makes workflow decisions a little tricky at the moment. One glaring issue is that consumer HDR displays don’t replicate the maximum brightness of professional monitors, so there is a question of mastering one’s work for the present, or for the near future when that higher capability will be more widely available. And where does this evolution stop? 4,000 nits? 10,000 nits?

Maybe a more pertinent creative challenge in the crossover period is which version to grade first, SDR or HDR, and how to produce the other version. There are a couple of ways to go about it, from using LUTs to initiate and largely automate the conversion to starting over from scratch and regrading the source footage in the new format.

One thought on “Our Virtual Color Roundtable”

Thanks for putting all of these great perspectives on one page.
Glad to here a lot of people are still trying to grasp all this newer tech.
I would also like to hear from the DP’s too regarding if and how they are adjusting to HDR request.
Your article is by far the most comprehensive article I have read on the changing Color Science technologies.
Keep up the Great work!
